Biometric Match

This is the name given to the the decision that a biometric sample and a reference template stored in a biometric database comes from the same human source, based on their high level of similarity.

A biometric match may consist of a score which designates the degree of similarity between the sample and the reference template. Typically, a match should never be identical; freshly gathered samples will inevitably vary somewhat from the reference template, due to subtle changes over time and errors in the process of feature extraction.

Some biometric systems may flag an exact match as a potential fraud; presenting an exact match implies that the reference template database has been compromised. The sample must score above the predetermined biometric match threshold.
